Why can’t we stop overeating during the festive period?

过节虽好,可我们为什么总是管不住嘴

The week between Christmas and New Year plays havoc with our waistbands. So why do we keep piling more and more on to our plates?

圣诞和新年之间的这一周让我们的裤腰变得更紧了。那么我们为什么还要不停的向自己的盘子里夹菜呢?

Between Christmas Day and New Year’s Eve, the average Brit gains 6lb – not surprising, given all the chocolate, cheese and turkey eaten in the aftermath of the 25th, a day when most people consume three times as much as usual. But why do we reach for an extra mince pie when we are fit to burst?

圣诞节和元旦之间这段时间,英国人平均重了6磅——这一点也不值得奇怪,想一想在25号后吃过的那些巧克力、乳酪和火鸡,差不多每人吃了比平时多3倍的食物。但是为什么我们快撑破胃的时候,还有再挑战极限般的再吃一个肉饼呢?

It’s because the brain mechanism that makes you hungry, driven by the levels of salts and sugars in our bloodstream, is not the same as the system that makes us stop eating. If we carried on eating until blood sugar levels returned to normal, we’d probably explode as it can take over half an hour for the effects of a meal to reach the bloodstream.

这是由于大脑机制的原因,大脑受血液中的糖和盐的含量驱使,糖和盐的含量不足时,你就会感觉到饿,这种机制和让你停止进食的原理不一样。如果我们等到血液中的糖含量回到正常时才停止进食,很可能我们的身体已经达到极限了,因为糖分要在吃过饭后半个多小时后才会溶解到血液中被吸收。

So, instead, the brain uses previous experience to predict when we should stop and makes us feel ‘full’ at the point when we’ve eaten just enough.

所以,相反的,大脑用以前的经验来帮助我们预测什么时候应该停止进食,而且让我们在吃的足够多的时候感觉到饱了。

However, this neurological system works better for some people than others, depending partly on our genes. Lots of factors can interfere with this prediction of when we’ve had enough: drinking alcohol, conforming with those around us, boredom, anxiety or excitement.

然而,由于每个人的基因不同,这一神经系统在一些人身上的表现要比其他人更为灵敏。很多因素会影响这种预测的准确性:比如喝酒、顺从我们周围的事物、无聊、焦虑或者兴奋——一都会影响到这种预测的准确性。
